Fix regression causing ICE for structs with VLAs [PR 112488]
A previous patch that fixed several ICEs related to size expressions
of VM types (PR c/70418, ...) caused a regression for structs where
a DECL_EXPR is not generated anymore although reqired. We now call
add_decl_expr introduced by the previous patch from finish_struct.
The function is revised with a new argument to not set the TYPE_NAME
for the type to the DECL_EXPR in this specific case.
